Accu fence the same as Biesemeyer Commercial?

I have an early sixties Delta Unisaw 34-450 that has the original Jet-Lock fence with the shorter tubes. I would like to install a 50” Biesemeyer but they are really expensive. I found for sale, a new “Powermatic Accu Fence” fence only and it appears as though it is the same as the Biese. Can someone comfirm if this is accurate? My plans are to acquire the PM fence and purchase the rails from Biesemeyer for my Unisaw if they are compatible. I thank you all in advance for your input.Doer
